一种内酰胺基团修饰的金吸附树脂的制备方法

Preparation method for gold adsorption resin modified by lactam radical

Abstract

The invention provides a preparation method for gold adsorption resin modified by a lactam radical. The preparation method comprises the following steps: introducing a complexing radical into polymerization, and obtaining a product after performing chloromethylation, amination and carboxylated reaction. The product disclosed by the invention comprises a functional group-N-vinyl pyrrolidone, a five-membered ring lactam structure is introduced into polymerization to form a complex with gold ions on a resin framework, so that the adsorption effects of the gold ions are strengthened. The complexing radical is firmly combined on the resin framework, not prone to dropping, capable of being used for a long time, and prolonged in service life.
本发明提供了一种内酰胺基团修饰的金吸附树脂的制备方法。在聚合中引入络合基团,再经氯甲基化,胺化,羧酸化反应,得到产品。本发明产品含有功能基团-N-乙烯基吡咯烷酮,通过在聚合中引进五元环内酰胺结构,可与金离子在树脂骨架上形成络合物,增强对金离子的吸附效果。该络合基团在树脂骨架上结合牢固,不易脱落,可长期使用,提高了使用寿命。
